AI Security Review
scanned 6d ago · by lpm-firewall-aiThe manifest has no install lifecycle hooks, and the flagged editor writes are reached through the user-invoked installer. Antigravity’s generated watcher is not activated automatically, while confidential account proof is sent to the package’s own service during an explicitly requested session.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs `install` to wire editor integrations, or runs `confidential` to start an account-approved session for a named brain.
Impact
Expected configuration changes and authenticated requests for the requested features; no automatic install-time data collection or activated persistence was identified.
Mechanism
Editor adapters write configuration and helper files. The confidential session sends account proof with the user’s Agnoclast token to the package service; Antigravity’s watcher requires a separate manual activation command.
AI rationale
The manifest has no install lifecycle hooks, and the flagged editor writes are reached through the user-invoked installer. Antigravity’s generated watcher is not activated automatically, while confidential account proof is sent to the package’s own service during an explicitly requested session.

Decision evidence
public snapshotAI called this Clean at 93.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json declares no install, preinstall, or postinstall hook.
- Antigravity wiring runs through the explicit `install` command and adapter call.
- Antigravity writes a helper script and LaunchAgent plist, but requires a separate `launchctl load` command to activate the watcher.
- The `confidential` command starts a session for a named brain; its account proof is sent to Agnoclast’s confidential-session endpoint using the user’s token.
